hi everybody
is the bandwidth related to disk space , because the one who is going to create me website he said , its enough only 100MB of space to get from webhost, I have nearly for now 30MB of videos besides his work he said 20MB, someone else he told me, your website will go down after exceeding the bandwidth limit , so what do you think ???

Bandwidth is the measurement of how much data your website viewers download when they watch a video (for example). So if your web host allows 100 MB of bandwidth, once your users have cumulatively downloaded 100MB of videos, pages or whatever is on your site, the web host will likely suspend access to your site until the next billing cycle begins.

This is *not* related to how much storage/disk space you need to host your videos. You may only need 30MB of disk space on the web host but you could need 500MB of bandwidth to accommodate your users. Most web hosts are kind enough to allow you upgrade your bandwidth so you can start out small and upgrade as you see fit.
